IMIROVEIVIENI IN HYDRANTS.

TO` ALL WHQM IT MAY CONCERN:

Be it known that we, WILLIAM I?. Drcmnsolv, DAVID S. WrrMAN, and GEORGE W. RABoLD, of the city of Reading, in the county of Berksn the State of Pennsylvania, have invented a new and useful improvement in Hydrants and Fire-Plugs, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, which make part of this specification, and in which- Figure 1 represents a perspective view of our hydrant.

Figure 2 a sectional elevation of the globe-valve case and lock A and M.

Figure 3 a plan view of the valve M.

Figure 4 a sectional elevation of our system of hydrant'as applied to fire-plugs.

Figure 5 a plan view ofthe valve M applied to same.

' The nature of our invention consists in providing hydrants or fire-plugs with cocks composed of a selflubricating valve moved by the ordinary key-rod, said valve being encased into a log-box we term a globe-valve case, on account of its peculiar shape, the whole so iixedand contrived as to prevent entirely sand, dirt, or any sediments to get access to or inside the joints or workings of the valve and cock, and also to keep said cock in perfect state of constant lubrication. Again, our invention, when applied to hydrants destined to be used especially as tire-plugs, has for object, as we will hereinafter describe, to open or close easily the plug by means of a peculiarly-gearing key, thus avoiding the back action which generally takes place when suddenly cutting oi the water.

To enable others skilled in the art to make and use ourinvention, we will now describe its construction and operation l Similar letters referring to similar parts all through the following description.

D is a goose-neck coming from the hydrant, and hears a thread in its inside head mouth, andi on which our globe-box A is screwed and set. A is provided in a a, figs. 1 and 2, with a thread, on which we screw cover or cap D' D', bearing valve M. lValve M is'a metallic disk, on -one face (the upper) of which have been cut recesses and holes fff, for the purpose hereinafter explained. A circular hole is punched or bored through disk M, and of a diameter equal to that of the inside of discharge pipe B'. lThe c'ap or cover D D is a. solid piece of metal in form of adisk, bearing on its upper centre an upright casing-block, E, through which passes valve-rod K, and on the head-of-E is set a spring, which, by means of a small pin running through rod K, has for object to secure valve M in permanent and water-tight friction with under surface of D' D. Valve M being prepared ns aforesaid, we ill up recesses and holes fff with tallow, and we set the valve in place as shown inrgs.

l and'4. In the appropriate place on cap D' D', by one side of casing-block E, is bored hole x fr, bearing inside thread on which. sets discharge pipe B, and a fitting-key, R, set on square head of rod K or hydrant-valve, is now ready for action. Valve M must be so set on that when closed'holc m is faced or blocked up by the'under face of cap D D' on which it rests, and when open hole m must correspond exactly with discharge pipe :e: xB. Now the water from the hydrant presses up with force against valve M, which presents to said water a rather broad surface, and therefore said pressure renders more perfect still the close fitting of valve M against cap D D'; and as the water has no other egress but through hole m, now closed by portions of plane under face of D' D', it (the water) can by no means have any waste, and will not keep the hydrant-box or the ground around it in the usual disagreeable state of wet and dampness. Again, the perfect fitting of the two disks of cap D' D' and valve M, insured, as mentioned before, by spring on head of block E, and the upward pressure of the water, leave no room whatever for any agglomeration of sand, dirt, n1ud, gravel, lite., which in a very short time will wear out of order the generality of hydrants and hydrant-cocks in use.V A permanent and perfect lubrication is also insured by the tallow which we insert -in recesses and holesfff, as above mentioned, and which, by its permanent contact with both surfaces of the joint formed bydislrs M and cap D' D', makes said joint perfect and water-wasting proof. When, as shown in figs, 4 and 5, our system is applied to lire-plugs, we connect the key-rod with the valvefrod by means of a cog-wheel lever and a iive-teeth pinion, which insures us against the bad and ruining effect cf the back action which invariably takes place in closing suddenly any ordinary water-valve or cut-otl`.

The main advantages derived from our system are a Water-ivasting proof` valve, and a perfect joint, a selflubricating valve, an easy motion to open or close, and no Wear whatever resulting of sand, dirt, or other sediments, which cannot accumulate o1' agglomerato in any part or parts of our system.

Having thus described our invention, whatwe claim as our invention, and desire to secure lay-Letters Patent of the United States, isf-v 1. Valve M, in combination with its lubricator, recesses and bolos, dischargelhole m, constructed and arranged in the manner and for the purpose above described.

2. The combination of valve M, lubrieator, reces`ses, and holes fff, valve-rod K, and key-rod R, globe-case A, and'goose-neck D,lconstructed, arranged, and operating together in the manner and for the purpose above described and set forth. 3. The key-rod R, combined with valve-rod K by means of a cogged lever and ve-teeth pinion, as above described and for the purpose set forth.
